accompanying drawings.

This invention is for a device for regulating a supply of gas or other fluid by means of a valve, the seating of which is opposed by a head of water, the device operating in such a manner that the gas passing through it is accurately controlled to give a constant pressure, while upon the failure of the water the gas or other fluid is shut off.

Another object is to provide a device of such nature which shall be eflicient, very simple in construction and have. no parts liable to become disarrangedor broken.

Another object is to provide a means for causing a uniform pressure of the water acting against the valve so long as any water is being supplied. 1

The above and other objects will become apparent in the following description in connection with the drawings, and the'essential characteristics are hereinafter set-forth in the claims.

Referring to the drawings, Figure 1 is a side elevation of my device, being partly broken awayto show the valve for the gas and the means for regulating the same; Fig.

2 is a plan of the device; Fig. 3 is a vertical transverse section on the line 3 -3 of Fig. 2 and Fig. 4 is a similar section on the line 44= of Fig. 2.

Referring to the drawings by reference numerals, 5 indicates a chambered base member, preferably a casting, having a passage 6 for water leading to a circular chamber 7. This chamber 7 is in communication With a passage 8 leading to, a vertical pipe 9 suitably mounted in a top wall 10 of a cham-* ber formed at the end of this passage. The chamber 7 has a circular opening 12in its upper wall, closed by a diaphragm 13 clamped in place between this wall anda flange 15 of the valve body, 16. body is shown as held to the base by suitable can screws 18. This diaphragm is attached at its center to a vertical valve stem 20, by

means of suitable washers 21 and a nut 22, as

shown. The valve body is provided withcates.

The valve pipe connections to which are fitted pipes 24: and 25, and the gas or other fluid is supplied through the pipe 24: to a chamber 26 Sepia..- rated from a chamber 27 by a wall 28. This wall is provided with a suitable opening for the passage of gas adaptedto be closed by a valve head 30, rigidly mou ted on the valve stem 20. Atits upper side the chamber 26 is provided with a threaded pening into which is fitted a plug 32 having a ShQlF-t ax a e 33 p o i ng a guide for the .9- per end of the valve stem. The lower end; of the valve stem' guided by passing loosely through-the base at the lower wall.

' of the chamber 7.

The water is fed to the chambered mem-f ber.5 through a suitable Pipe 35-.-.through the passage. 6 to the chamber 7 ,the passage 8 and upwardly through the pipe 9, over; flowing at the open top thereof and returning downwardly outside of the pipe 9, and within a tube 36 mounted in the upper portion of a chamber 38 with. which it communi- This chamber opens into a passage 39 leading downwardly to a suitable exit passage or pipe 40. A vent opening 37 in the pip'e36 allows a free'downward flow of water to the exit passages. Thus the column ofrwater within the pipe 9 provides a unis form head or pressure bearing upwardly on the diaphragm 13 to normally hold the valve 30 off of its seat while the water is being supplied to the device. This allows the passage of gas through the pipes 24 and 25. Upon the failure of the supply of the water to the device, the water within the chamber will drain'through the opening 44, removing the upward pressure from the diaphragm 13 allowing this diaphragm to resume its normal position under the weight of the valve and stem and the gas pressure on the dialing valvesho'wnand described in the application of Harrison H. Southworth and myself, Serial No. 741,4:14, filed January 11, 1913, Byprcvidingasuitable lever or other mechanism adapted to engage the lower end of the valve ste n'by means of a collar such as shown at 42, the device may be applied to a refrigerating apparatus such as shown and described in the application of Harrison l-l. Southworth, No. 837,118, filed March 8, 1914. It is to be understood, however, that I do not wishto be limited to such uses of my device. When applied to a refrigerating apparatus such as shown in the application, the cooling water for the apparatus is supplied through thepipe 35 and overflows through the outlet 4:0. Upon; the failure of this cooling water it is desirable to shut ofl at once the fuel gas supplied to the burner of the apparatus through the pipes 24 and 25 and the valve 16. It will be seen that this shutting ofi of the gas would occur immediately upon the failure of the supply of water through this pipe, as the water would drain from the chamber 7, through the guide opening at 44: about the lower end of the valve stem, there'- by removing the pressure on the diaphragm allowing the valve to seat itself.

. l-lavingthus described my invention, what .I- claim is:

1. In a gas regulator, the combination of a conduit for gas, a valve therein, a diaphragm connected with the valve, a water passages way beneath the diaphragm, an upright tube open at its upper end and connected at its lower portion with the space beneath the diaphragm, an outer casing surrounding the tube and providing an overflow passageway therefor, and conduits for conveying water to the tube and from the outer casing,

2., In a gas regulator, the combination of a casing having a valve seat and an opening below the seat and intake and exit passages one above the seat and the other below the seat, a diaphragm across the opening referred to, a chamber for fluid below the diaphragm, a casing communicating with an. exit pipe for liquid, an internal upright tube within said casing having an opening at its upper end into the casing and having its lower end in communication with the space beneath the diaphragm, and means foradmitting liquid to said space.

3. In a gas regulator, the combination of a conduit for gas, a conduit for water, a valve in the gas conduit, a diaphragm between the water and gas conduits, connections between the diaphragm. and the valve, a tube provid ing a water column of suificient height to meager cause the water to raise the valve from. its seat, and an outer casing freely surrounding the tube and providing an overflow.

4. In a gas regulator, the combination of a conduit for gas, a conduit for water, a valve in the gas conduit, means whereby the water pressure may act on the valve to raise the same, an internal vertical passage in said water conduit providing a water column causing a. pressure of the-water on said means, a passage embracing said. vertical passage and leading to an exit opening whereby the water may overflow from said water column passage,

5. In a gas regulator, the combination of a gas valve, conduits leading thereto and therefrom, a chambered casing 011 which said valve is mounted having a passage for water, means in said casing connected with the valve whereby water premure may raise the column, a tube outside said tube providingan overflow passage, and an exit opening in communication with said overflow passage.

6. In a gas regulator, the combination of a gas valve, pipe connections leading thereto and therefrom, a casing on which said valve is mounted having a water passage therein, a pipe leading to said water passage,a chamber for the water beneath the valve, adiaphragm closing the upper portion of said chamber, connections between the valve and said diaphragm, a vertical passage connected with the water passage providing a water column above the diaphragm, and a vertical tube outside said first mentioned tube providing an overflow passage around the same.

7. In a gas regulator, the combination of a gas valve, conduits leading thereto and therefrom, a casing on which said valve is mounted-having a water passage therein, a conduit leading to said water passage, a chamber for the water beneath the valve, a diaphragm closing the upper portion of said chamber, connections between the valve and said diaphragm, a vertical passage connected with the water passage providing a water column above the diaphragm, a vertical tube outside said passage providing an overflow passage around the same, and exit openings in communication with said overflow passage and said chamber for draining the same.
